Application filed October '24, 1919. Serial No. 333,101.

'7 citizen of the Republic of France, a resident of Paris, in the Republic of France, have invented new and useful Improvements in or Relating to Guns Mounted on Wheeled Carriages, which invention is fully set forth in the following specification.

Wheeled gun carriages are known which are so constructed as to allow of the carriage body havinga limited range of lateral movement between the wheels for the purpose of varying the training of the gun.

In those known gun carriages the said lateral movement is produced generally. by the operation of a screw journaledin the head of the gun carriage, and working in a nut fixed to the carriage axle.

According to the present invention, the head of the carriage, instead of sliding directly along the axle, is constructed to slide along a cross-piece or auxiliary axle, for instance as a result of the operation of a screw working in a nut carried by the said crosspiece. Springs for supporting elastically the combined gun carriage'and cross-piece or auxiliary'axle during transport, are arranged between the said cross-piece and the axle or between the gun carriage body and the axle. Movable locking pieces permit in one case the cross-piece or auxiliary axle, and in the other'case the carriage body, to beardirectly upon the axle in firing.

Shortly described, the present invention consists in providing means for slidingthegun carriage along the axle for the purpose of altering the tra1n1ng, wh1le at the same time providing means for suspending elastically the gun carriage during transport.

Various constructlonal forms of this nin the accompanying drawings.

In the known wheeled gun carriage constructed to permit the sliding of the car-- riage along the wheeled axle for training purposes, as shown in Fig. 1, A is the un carriage axle carrying the Wheels B, B. C are the side frame plates of the un carriage, in which is journaled a screw working in a nut E that is fixed to the axle A.

The lateral motion of the carriage C. for

o r the purpose of altering the training, is. pro- Figure 1 is a plan partly in horizontal section of the usual ordinary wheeled gun carriage constructed to allow' of the carriage sliding along the axle for the purshown in Figs. 2-4: of this invention, the sliding motion of the carriage C'C, instead duced by actuating the screw D by means 1 of a suitable gear terminating for'instance at a bevel pinion cl.

According to the constructlonal form their axle A. On each end of the false axle F,

l boxesC which are fixed to the carriage side A through the medium of elastic suspensory devices, so that in transport, the arrange- Inentv provides an elastic suspension .,-of a combined gu'n carriage and falseaxle F upon the axle A. i

In the example shown, the'axle A carries two cross-pieces G to the ends of which are pivotally jointed the links H. To the other end of these links are pivotally connected the ends of the longest leaf of a pile of leaf-springs I the buckle J of which is carried by the false axle F.

The springs I are adapted to be rendered inoperative during firing. For this purpose locking pieces K working in the cross-pieces G, are adapted to be brought into contact with blocks J 'by the screwing of their in:

ternal screw-threads along a screw L which is journaled in the axle A and which is operated by means of a key.

The transverse movements of the false 7 axle F during transport, can be limited by means of spring buffers M,'.N, lodged in recesses formed in 'the ends' of the said false axle F. These spring buffers also serve to absorb the jar occasioned by the transverse movement of the carriage on the auxiliary axle.

A connection between the false axle and the carriage wheel axle for the purpose of drawing the latter along during transport,

'may be roduced as shown, by holding the false ax e between two pairs of jaws C fixed to the carriage side frame plate-C. Further, the outer ends of the buffers M are constructed as forks embracing between prongs projections formed on the axleA. m I

In the example just described, the axle A combined with the false axle F, is made as shown of a dropped frame formation hav ing a straight horizontal cross-piece and vertical arms, so as to enable the false axle to be situated on a level with the axle body.

In the constructional form shown in Figs. 5'8, the false axle F is arranged substantially in the horizontal plane of the straight between two collars f, i, there is provided a bracket 0 serving as a'support by means of a stirrup piece 0 for a leaf-spring I, the

lower bundle of sprin s of which is attached by means of a block a to the axle A. The bracket OO two slides 0 The arrangement comprises,

K which allow of reliev ng the springs in rectly u on the axle ,A. These] locking pieces are guided in this construction in plates C; and are carried by operating screws L working in tapped screw-threads in the said boxes.

To slide the carriage for the purpose of is guided on the axle A by' in the previous example, lockingpie'ces altering the training of the gun, the false axle F comprises, as in the preceding example, a nut E, not shown, in'which a screw D is adapted to work that is the carriage side plates C.

The blocks G are preferably held between two collars a of the axle A.

Figs. 9 and 10 show another constructional example wherein the false axle F has the form of a sleeve surrounding the carriage axle A.

journaled in The elastic suspension between the axle A and the false axle F comprises leaf sprin I'connected by links H. The-lower bund e of springs is attached by means of a block G to the axle A, while the upper bundle of springs bears against the bottom of a stirrup 0 -0 slipped on the end of the tubular false axle F. In this arrangement, the blocks G are guided in the stirrups O. The locking pieces K are formed on the ends of screw spindles L working' in 'a tapped screw-thread formed on the stirrup 0 -0.

Figsqll, 12 and 13show a constructional.

formwherein the combined carriage C'and false or .auxiliary axle F on which the latter slides for altering the training, are suspended elastically by sprin tween the carriage bod y.

C and the main wheeled axle A.

With this object, the carriage body is pit o1,

vided with brackets C C to whichare pivoted links H that are pivoted at their other ends to the top leaf of the bundle of s rings I that are connected in their mid 1e by blocks G mounted on the square axle A in such a manner as to be capable of sliding along the'latter. This axle is formed with two slots A through which pass rods having. their screw threaded upper portions L engaged in a tapped locking piece K which can be brought into contact with the carriage-body insuch a manner as to relieve the springs I during the firing. The locking pieces K are uided in lodgments G projecting from t e blocks G.

In this example the carriage wheel axle A is dropped or U-shaped, as in the example shown in Figs. 2 to 4,"and thefalse orf of the gun carria e. In this sliding moveas Well as the rods L. carrying the locking. pieces K, are moved mentthe blocks to slide along the vcarriage wheel axle A. The axle A is takenalong for transport by the same means as shown in the example illustrated in Figs. 2 to 4.

s I interposed be-' In placing the gun for firing, the tail of the carriage trail (not shown) is pivoted to the ground inthe usual manner. Preliminarily to firing,the bolts L are turned to move the members K to form a direct hearing between the twoaxles, v.or between the carriage and the main axle, to relieve the springs of the load of the carriage. In training the gun, the headof the carriage'is moved along the auxiliary axle F to the desired position. During this adjustment of the carriage head, the carria e, as a Whole, pivots on the anchoredtail or the trail. As the gun is trained, the movement of the carriage head along the auxiliary axle will cause a slight shifting in the position of the main axle relatively to the trail pivot and the supporting wheels B will turn slightly to accommodate this shifting of the main axle. Preliminarily to transport, the carriage is moved to midway position on the auxiliary axle and the bolts L are turned to move the plates K to eliminate the direct bearing between the main axle and the auxiliary, or between the main axle and the carriage, thereby interposing the springs I to carry the load of the carriage.
